Polycyclic aromatic hydrocarbons (PAH) are a large group of compounds made up of two or more fused benzene rings. They are primarily formed by incomplete combustion or pyrolysis of organic matter and during various industrial processes. Consequently, they are found in automobile exhaust, smoke from fires or cigarettes and as a component of air pollution. PAHs generally occur in complex mixtures which may consist of hundreds of compounds.
